Intelligent switching traffic light according to vehicle proportion in waiting for passing of each intersection

Abstract

The invention discloses an intelligent switching traffic light according to the vehicle proportion in waiting for passing of each intersection, and relates to the technical field of traffic management facilities. The intelligent switching traffic light comprises an intelligent traffic light control system host, buried vehicle induction coils, a signal line and traffic lights. The intersection is provided with four traffic lights. The intersection is provided with the buried vehicle induction coils in the eastern, southern, western and northern directions. Each buried vehicle induction coil is composed of an intersection near-end induction coil and an intersection far-end induction coil. The intersection near-end induction coils and the intersection far-end induction coils are connected with the intelligent traffic light control system host through the signal line. The intelligent traffic light control system host is connected with the traffic lights. The intelligent switching traffic light according to the vehicle proportion in waiting for passing of each intersection is reasonable in structural design and can perform efficient and optimized adjustment and control of on / off time of the traffic lights of each intersection anytime so that the urban traffic pressure can be effectively alleviated and the passing efficiency of the traffic intersection can be enhanced.

Description

technical field [0001] The invention relates to the technical field of traffic management facilities, in particular to traffic lights that are intelligently switched according to the proportion of vehicles waiting to pass at each intersection. Background technique [0002] For the red, yellow and green traffic lights currently widely used in cities, it is rare to see them as intelligent traffic lights, although many engineers and invention enthusiasts have spent a lot of effort on it and thought of a lot of good ideas. , but the current actual application situation is very pessimistic. With the substantial increase of the total number of various vehicles in our country, the traffic pressure on urban roads in various places is close to serious overload, but our current situation is: still widely used in a large number of land In the conventional traffic signal light control system, although the system also adopts the light switching control technology with single-chip or PLC ...

[0002] For the red, yellow and green traffic lights currently widely used in cities, it is rare to see them as intelligent traffic lights, although many engineers and invention enthusiasts have spent a lot of effort on it and thought of a lot of good ideas. , but the current actual application situation is very pessimistic. With the substantial increase of the total number of various vehicles in our country, the traffic pressure on urban roads in various places is close to serious overload, but our current situation is: still widely used in a large number of land In the conventional traffic signal light control system, although the system also adopts the light switching control technology with single-chip or PLC as the core, the interval time control of each intersection is still based on the manual preset value, so for Improving the traffic efficiency of traffic intersections lacks effective effects, and frequent manual modification of the switching time of traffic lights cannot meet the new situation of constantly changing vehicles passing at intersections, and the labor and other costs are also unbearable

[0003] At present, the design schemes of some intelligent traffic lights that have been disclosed on the Internet are mostly limited to using video camera and image processing methods to judge the traffic flow situation or pedestrian traffic situation in all directions at the intersection, or expect to be able to control traffic on each vehicle. Install a wireless transmitting module and install a wireless receiving device in the traffic signal light system to judge the number of cars entering the intersection. These methods have relatively large limitations and design problems, and it is very difficult to actually implement them. According to the analysis, the difficulty and key point to realize the intelligent traffic lights in the true sense is to find an economical and effective statistical method for the number of vehicles waiting to pass at each intersection. Vehicle proportions and intelligent switching of traffic lights are still necessary
